             Summary: Handle large keystores in SslEngineValidator
                 Key: KAFKA-15502
                 URL: https://issues.apache.org/jira/browse/KAFKA-15502
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 3.6.0
            Reporter: Manikumar
            Assignee: Manikumar


We have observed an issue where inter broker SSL listener is not coming up for 
large keystores (size >16K)

1. Currently validator code doesn't work well with large stores. Right now, 
WRAP returns if there is already data in the buffer. But if we need more data 
to be wrapped for UNWRAP to succeed, we end up looping forever.

2. Observed large TLSv3 post handshake messages are not getting read and 
causing UNWRAP loop forever. This is observed with JDK17+
